The sentence "Set the LC_CTYPE locale to the user preferred locale." should end with a period
instead of a question mark.

gh-96746: Docs: Clear up Py_TPFLAGS_DISALLOW_INSTANTIATION inheritance (GH-99002)
The flag is not inherited, but its effect -- a NULL tp_new -- is.
Drop hints for people who come here wanting to “disallow instantiation”.

The definition of obj in the `Py_buffer` struct is as a PyObject*
ec091bd47e/Include/pybuffer.hGH-L22
PyMemoryView_GET_BASE returns `.obj` - thus its return type
should be a PyObject* (or at least a void*). It definitely
doesn't return `Py_buffer`

Nowadays everything that *is* in the Limited API has a note added
automatically.
These notes could mislead people to think that these functions
could never be added to the limited API. Remove them.

Use _Py_CAST() and _Py_STATIC_CAST() in macros wrapping static inline
functions of unicodeobject.h.
Change also the kind type from unsigned int to int: same parameter
type than PyUnicode_FromKindAndData().
The limited API version 3.11 no longer casts arguments to expected
types.

Add the -P command line option and the PYTHONSAFEPATH environment
variable to not prepend a potentially unsafe path to sys.path.
* Add sys.flags.safe_path flag.
* Add PyConfig.safe_path member.
* Programs/_bootstrap_python.c uses config.safe_path=0.
* Update subprocess._optim_args_from_interpreter_flags() to handle
the -P command line option.
* Modules/getpath.py sets safe_path to 1 if a "._pth" file is
present.
Convert the following macros to static inline functions:
* PyByteArray_AS_STRING()
* PyByteArray_GET_SIZE()
* PyBytes_AS_STRING()
* PyBytes_GET_SIZE()
Limited C API version 3.11 no longer casts arguments.
Add _PyBytes_CAST() and _PyByteArray_CAST() macros.
Py_REFCNT(), Py_TYPE(), Py_SIZE() and Py_IS_TYPE() functions argument
type is now "PyObject*", rather than "const PyObject*".
* Replace also "const PyObject*" with "PyObject*" in functions:
* _Py_strhex_impl()
* _Py_strhex_with_sep()
* _Py_strhex_bytes_with_sep()
* Remove _PyObject_CAST_CONST() and _PyVarObject_CAST_CONST() macros.
* Py_IS_TYPE() can now use Py_TYPE() in its implementation.
* Revert "bpo-46850: Move _PyInterpreterState_SetEvalFrameFunc() to internal C API (GH-32054)"
This reverts commit f877b40e3f.
* Revert "bpo-46850: Move _PyEval_EvalFrameDefault() to internal C API (GH-32052)"
This reverts commit b9a5522dd9.
Move the private _PyFrameEvalFunction type, and private
_PyInterpreterState_GetEvalFrameFunc() and
_PyInterpreterState_SetEvalFrameFunc() functions to the internal C
API. The _PyFrameEvalFunction callback function type now uses the
_PyInterpreterFrame type which is part of the internal C API.
Update the _PyFrameEvalFunction documentation.
* `PyFrame_FastToLocalsWithError` and `PyFrame_LocalsToFast` are no longer called during profile and tracing.
(Contributed by Fabio Zadrozny)
* Make accesses to a frame's `f_locals` safe from C code, not relying on calls to `PyFrame_FastToLocals` or `PyFrame_LocalsToFast`.
* Document new `PyFrame_GetLocals` C-API function.
Add new functions to pack and unpack C double (serialize and
deserialize):
* PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8()
* PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8()
Document these functions and add unit tests.
Rename private functions and move them from the internal C API
to the public C API:
* _PyFloat_Pack2() => PyFloat_Pack2()
* _PyFloat_Pack4() => PyFloat_Pack4()
* _PyFloat_Pack8() => PyFloat_Pack8()
* _PyFloat_Unpack2() => PyFloat_Unpack2()
* _PyFloat_Unpack4() => PyFloat_Unpack4()
* _PyFloat_Unpack8() => PyFloat_Unpack8()
Replace the "unsigned char*" type with "char*" which is more common
and easy to use.
* C API docs: move PyErr_SetImportErrorSubclass docs
It was in the section about warnings, but it makes more sense to
put it with PyErr_SetImportError.
* C API docs: document closeit argument to PyRun_AnyFileExFlags
It was already documented for PyRun_SimpleFileExFlags.
* textual fixes to unicode docs
* Move paragraph about tp_dealloc into tp_dealloc section
* __aiter__ returns an async iterator, not an awaitable
This reduces the size of the data segment by **300 KB** of the executable because if the modules are deep-frozen then the marshalled frozen data just wastes space. This was inspired by comment by @gvanrossum in https://github.com/python/cpython/pull/29118#issuecomment-958521863. Note: There is a new option `--deepfreeze-only` in `freeze_modules.py` to change this behavior, it is on be default to save disk space.

When Python is embedded in other applications, it is not easy to determine which version of Python is being used. This change exposes the Python version as part of the API data. Tools like Austin (https://github.com/P403n1x87/austin) can benefit from this data when targeting applications like uWSGI, as the Python version can then be inferred systematically by looking at the exported symbols rather than relying on unreliable pattern matching or other hacks (like remote code execution etc...).

The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code.
This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.
Rename PyConfig.no_debug_ranges to PyConfig.code_debug_ranges and
invert the value.
Document -X no_debug_ranges and PYTHONNODEBUGRANGES env var in
PyConfig.code_debug_ranges documentation.
It is now considered a historical accident that e.g. `for` loops and the `iter()` built-in function do not require the iterators they work with to define `__iter__`, only `__next__`.
Objects that support garbage collection ("container" objects) should
call PyObject_GC_UnTrack() from their destructors before clearing any
fields which may point to other "container" objects.
Add PyThreadState_EnterTracing() and PyThreadState_LeaveTracing()
functions to the limited C API to suspend and resume tracing and
profiling.
Add an unit test on the PyThreadState C API to _testcapi.
Add also internal _PyThreadState_DisableTracing() and
_PyThreadState_ResetTracing().
Replace old names when they refer to actual versions of macOS.
Keep historical names in references to older versions.

Add the Py_ALWAYS_INLINE macro to ask the compiler to always inline a
static inline function. The compiler can ignore it and decides to not
inline the function.
Convert the Py_TYPE() and Py_SIZE() macros to static inline
functions. The Py_SET_TYPE() and Py_SET_SIZE() functions must now be
used to set an object type and size.
